JOSEPH F. SVAB, OF CEDAR RAPIDS, IOVA.

CHURN.

SPECIFICATION forming part of Letters Patent No. 328,083, dated October13, 1885.

Application filed April 24, 1885.

To all whom, t may concern:

Be it known that I, JosErH F. SWAB, a citizen of the United States,residing at Cedar Rapids, in the county of Linn and State of Iowa,haveinvented certain new and useful Improvements in Churns, of which thefollowing is aspecication, reference being had therein to theaccompanying drawings.

Myinvention relates to Creamery testers and churns; and the object of myinvention is to provide devices for receiving cream, securing them bysimple and efficient means in a churn, and giving a peculiarly combinedrotary and oscillating motion to the churn. Cream-testers are used increameries and butter-factories to ascertain the amount of butter in aquart of cream furnished by' different farmers, thelatter being paidduring the following month, according to the proportion of butterobtained from said quart. The cream is put in half-gallon jars, properlynumbered or marked with the name of each farmer, and churned for a givenlength of time. These jars in this ease are secured in a double framemade for the purpose; but a single frame may also be secured to a churnand given the same peculiar motion.

The invention will rst be hereinafter fully described, and thenspecifically set forth in the claims.

Figure 1 is a perspective view of my improved cream-tester and churn.Fig. 2 is a vertical section of the same. Fig. 3 is amodifi cation ofFig. 2 in vertical section. Fig. 4 is a side elevation of the crank-armas shown in Fig. 1, and Fig. 5 is a modification of the fastenings usedto retain the jars in the creamtester or churn shown in Figs. l and 2.

Like letters refer to like parts in all the figures.

In the drawings, A and A representthetwo side uprights,provided withbraces Aresting upon cross-beams At, connected together by two parallelbeams, A5, and braces A, to form a solid foundation for the tester andchurn. Through the two uprights or other suitable bearings passes thecrank-shaft B. Said shaft has adjacent to the inside of one of theuprights two crank-arms, B', connected by a crankpin, and on the outerside of the upright A the shaft is provided with a pulley, B2, fromwhich it receives its motion. The upper por- Serial No. 163,296. (Nomodel.)

tions of the uprights A and A have perforations,which act as bearingsfor the journals C, secured to the sides of the tester or churn D. Thejournal C adjacent to the upright A is provided with and extends betweenthe crankarms C, and the two crank-arms B and C are united by theconnecting-bar C2, the ends of which are perforated to receive thecrank-pins c and c.

The tester or churn can be made of different shapes. In Figs. 1 and 2 itis presented as having four compartments and as being oblong in form,having itsjournal-carrying sides D adjacent to the two uprights A and A.The sides D' are connected to a middle strip, D3, by j hinges d, andheld in position by catches or hooks d, engaging with eyes attached tothe sides D. The tester or churn is provided with a partition, D2, and acentral Hoor or bottom, D3. The partition D2 is provided on both sideswith a series of shallow circular pockets, D4, to receive one end of aseries of tin or glass cans or jars, E. The hinged sides D' are alsoprovided with a series of circular pockets, D, immediately opposite thepockets Dtin the partition D2. If tin cans are used instead of glassjars, they have a glass gage in one side and extending nearly the wholelength of the can. Each can or jar is provided with a cork or stopper,e. The movement given by the crank-shaft B, connecting-rod C2, andcrankjournal C gives to the tester or churn a combined rotary and ajerky oscillating motion, that causes the cream placed in the cans orjars E to have its globules broken and be rapidly transformed intobutter, as the churn, by means of its crank arms and rod, receives firstan almost entire revolution in one direction until arrested by itsconnecting-rod striking against the shaft C, immediately followed by thesame amount of revolution in the opposite direction, giving a veryeffective churning motion to the cream.

The crank-arms upon the shafts may be secured thereon by set-screws ormay be made integral therewith.

In Fig. 3 the cream-tester or churn is represented as having a framecarrying series of cans or jars E and hinged sides D', as in Fig. 2, andabove it a water-tight box or creamreceptacle, F, provided with anopening hav- IOO ing a cover, F, properly secured in, to retain thecream in the churn-box F. Said churn can be used as a cream-tester, withcans or jars E, and as an ordinary churn,and receive the same rotaryoscillating motion explained in regard to Figs. l and 2.

To facilitate the removal of each jar independently of the others, theframe carrying the jars is represented in Fig. 5 as having pockets toreceive one end of the jars, and thumb-screws G, passing through platesg, secured to the top and bottom D', and covers or cap-pieces G areplaced at the top or bottom of the cans orjars E, and by the aid of thethumb-screws G hold them in place until their removal is desired.

'I am aware that churns have been mounted upon a crank-shaft to whichmotion has been transmitted through a connectingrod from a crank shaftof smaller radius, and that said churns have thus been made to oscillatewithin an arc of about one-third of a circle, and do tester or churn andits supports, the shaft B, provided with crank-arms B', and thechurnshaft C, having crank arms united by said shaft, with aconnecting-bar, G2, uniting the cranks of the shafts B and C, wherebysaid bar is arranged to strike and be arrested by the shaft C beforecompleting each revolution, iirst in one direction and then in theopposite, substantially as and for the purpose described.

2. The combination of a frame, having compartments provided with fixedsides, hinged ends, and catches, with the shaft C, having a crank-arm,the shaft B, having a crank-arm, and the connecting-bar G2, uniting thecranks ofthe shafts B and C and arrested by the latter shaft, wherebysaid bar is arranged to strike and be arrested by the shaft C beforecompleting each revolution, lirst in one direction and then in theopposite, substantially as and for the purpose described.

In testimony whereof I afiiX my signature in presence of two witnesses.

JOSEPH F. SVAB.
